Pneumatic Discharge Hammer Mills The grinding mechanism of this group is quite similar to the gravity discharge hammer mills. However, the pneumatic mills typically use a thinner hammer and the interior wall of the grinding chamber features a ribbed liner plate. This plate has a washboard effect on the material, and works in unison

Material with high stickiness creates problems in all aspects of the grinding process, including feeding (e.g., making metering into the mill difficult), grinding (e. g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials.
